As of December 2023, 27.6% of all purchases in the UK were made online. That number has only increased, with more and more customers preferring online payments.

If you’re starting your own business in the UK, then, you’ll need to be able to take online payments. In this article, we take you through the basics and summarise some of the best online payment platforms for small businesses available.

How to take payments online

There are a few different ways that small businesses can handle online payments.

  • Bank transfers are simple and understandable, but can seem unprofessional.

  • Direct debits allow customers to set up recurring payments, such as subscriptions and repeating invoices. They’re not designed for one-off payments, but work well if you’re collecting repeat payments.

  • Mobile payments allow customers to pay using their mobile, either on a website or at a point of sale.

  • Point-of-sale (POS) payments are payments taken at your physical location or online counter.

  • Online card payments are the most popular way for small businesses to take online payments, and they’re what we’ll be focusing on here.

Card payments are handled through online payment systems and can be made using a debit or credit card or directly from a customer’s bank account.

We’ll look at how to set up a payment system below, but you should know from the outset that however you do this, you can adopt a payment structure that suits your business. You have options that range from fixed monthly fees to pay-as-you-go models.

Typical fees are:

  • set-up: £20–£50 

  • transactions: 10p–30p per transaction 

  • percentage of monthly sales: 1.9%–4.0%

How do online payment systems work?

An online payment system is usually made up of three elements:

  • a payment gateway, which sends payments to the processor 

  • a payment processor, which handles the actual transaction 

  • a merchant bank, into which the customer’s funds are deposited before they are transferred to your business bank account

All-in-one payment platforms provide all these elements in a single package, making them a great solution for small businesses. 

Benefits of online payments

Using online payments has numerous benefits for small businesses. Some of the most important advantages include:

  • Convenience and accessibility: online payments offer customers the convenience of making transactions anytime, anywhere, using various devices such as computers, smartphones, or tablets.

  • Faster Payments: unlike traditional payment methods like cheques, which can take days or even weeks to clear, online payments enable instant or near-instant transfer of funds.

  • Security: Payment card industry regulations require all online payments to be SSL (secure socket layer) encrypted. Most systems will have their own SSL certificate, while website builders like Squarespace or Wix make it easy for you to get your site SSL certified.

  • Cost efficiency: electronic payments often incur lower transaction costs compared to traditional methods like paper checks. Businesses can save money on processing fees, mailing costs, and other expenses associated with manual payment processing.

Online payment systems make selling quick and easy, and provide good security on both ends.

Mobile payment systems

As smartphone security improves, more and more people are using their mobile devices for payments. Adopting these payment systems for your small business can make dealing with customers easier and quicker than ever.

Types of mobile payment include:

  • QR code payments - customers have to scan a QR code to open a payment window

  • mobile-to-mobile payments - allow for quick and secure payments using a mobile number but are less common for a business

  • magnetic secure transmission (MST) and near-field communication (NFC) payments - these require a physical device

Each of these is useful for in-person transactions, but mobile payments are also available online. Many online payment apps allow customers to use their mobile to complete their purchase, and most browsers allow mobile users to enter their card details as they would on a desktop.

How to set up an online payment system

When it comes to setting up an online payment system, businesses have several options.

Opening a merchant bank account

A merchant bank acts as a go-between, taking care of things like authentication.

Businesses choose the card companies they’ll work with and set up an account. When customers pay, they send money to the merchant bank, which then releases it into the business’s account.

The major advantage of this method is that it works out cheaper in the long term, as the merchant bank’s monthly and transaction fees are generally lower than those involved in other options.

However, merchant banks usually require you to sign a multi-year contract, and the process can be time-consuming.

Using an e-commerce platform

Many payment platforms for small businesses, like eBay and Etsy, have built-in payment processors. While you’re unlikely to see many big businesses using these sites, they can be perfect for small shops or self-employed sole traders.

Using an online payment app

An online payment app is perhaps the best option for small businesses, as it lets you get set up and start accepting payments quickly and easily. 

While transaction fees are high, using online payment apps can actually be cheaper for new businesses than setting up a merchant bank account.

In many cases, it’s best to start with a payment app and shift to a merchant bank account later on, when you’re more established.

Tips for deciding the best online payment service

If you need help deciding which online payment system is best for you, consider the following questions:

  • Does this payment app suit my business model (e.g. ecommerce or subscription)?

  • Will my customers recognise this payment system?

  • Does this app offer the payment options that my customers expect?

  • Is this payment system affordable for my size of business?

  • Do I expect to be taking international payments?

  • Can this payment system connect directly to QuickBooks?

Startups.co.uk and Merchant Savvy offer helpful comparisons of secure payment systems that might be suitable for your small business.

Online payment solutions FAQs

How do online payment systems work?

An online payment system typically consists of three main elements: a payment gateway, a payment processor, and a merchant bank. The payment gateway acts as an intermediary, transmitting payment information securely between the customer, the merchant's website, and the payment processor. 

The payment processor then handles the actual transaction, verifying the payment details and transferring funds from the customer's account to the merchant's account. Finally, the merchant bank, also known as an acquiring bank, receives the funds from the payment processor and deposits them into the merchant's bank account.

How can I set up an online payment system for my business?

Setting up an online payment system involves several options tailored to different business needs. One approach is to open a merchant bank account, which offers lower long-term costs but requires signing a multi-year contract and a lengthy setup process. Alternatively, businesses can use e-commerce platforms like eBay or Etsy, which have built-in payment processors suitable for small shops or sole traders. 

Another option is to use an online payment app, which provides quick and easy setup, although transaction fees may be higher initially.

Which online payment apps integrate with QuickBooks?

Several online payment apps seamlessly integrate with QuickBooks, allowing for direct payments from invoices. These include PayPal, renowned for its global accessibility, GoCardless and Zettle.
